` LOCK.

Application filed June 3D, 1921. Serial No. 481,605.

To all whom t may concer/n.'

Be it known that I, VILLTAM J. CARROLL, a citizen of the United States, residing in the city and county of NewI-Iaven, State of Connecticut, have invented certain new and useful Improvements in Locks, of which the following is a full, clear and eXact description.

This invention relates to locksand more particularly to improved controlling mechanism for the ldead'bolts or latch bolts of locks of the type employing winged keys. YVhile my improvements' may be found particularly useful with hotel locks or those having similar uses, it vwill be apparent that they are not coni-ined to this type of locks, but may be applicable to winged key locks ofany description.

It has been the usual practice heretofore to construct locks of this character in such a manner that a plurality of swinging or pivoted tumblers are provided to control the position of the bolt by engagement with a part of the bolt and which are in turn controlled by the key bit. At the same time that the tumblers are moved to inoperative position or to a position to release the bolt, the key bit engages talons upon the bolt stem to protract or retract the bolt.

In the embodiment of my invention which I have illustrated in the accompanying drawings, I have Vprovided a lock mechanism having an operating or controlling slide which engages the bolt to control the same and which is'in turn controlled by a suitable tumbler mechanism. It is to be noted, however, `that in my 'improved' construction this -tumbler mechanism does not engage the slide' itself, but-on the contrary engages and controls the positionof a detent which in turn controls the -position of the controlling slide. This Ydetent. is arranged to retain the controlling slide in either oit' its two extreme positions of movement and the detent can only be moved vfrom'v engagement with the slide when the tumblers have been actuated bythe proper key. The key bit at the same timeengages talons on the operating slide to impel this slide to its various positions.

; One object yof my invention is thejprovision of an-improved controlling mechanism for the bolt of the lock. f 1 .A further' object of my invention is to' to provide a detent to controlthe position' of this controlling slide and to arrange the tumbler mechanism so that the position of this detent will in turn be;c0ntrolled thereby.

Another object of my invention is to provide a Alock oi this character with tumbler mechanisms so arranged that it mayV be operated by a.- plurality of keys.

To: these and other endsthe invention consists in the novel features and combinations of Aparts to be hereinafter' .described and claimed. i

In the accompanying drawings:

v Fig. 3 is a view similar. to Fig.v ing the operation of the controlling mechanism Vas the bolt is beingmoved toprotracted position;

-Fig. 4 is a view similar to Fig. 2, but showing the controlli-ng mechanism from the opposite side and is a, section taken substantially upon line 4 4 of Fig.y 5;

Fig-.5 is a sectional view on line 5-5 of-Fig. l;

yFig. 7 is a sectional view on line'7-7 of Fig.2;and n Fig. 8 is a perspectiveviewof thefbits of some of the keys adapted to be usedl with my improved lock. r

While I havechosen to show my improved lock-'mechanism in connection with what is commonly knowny as a mortisey lock,.it ywill be apparent that the principles` ofthe invention :may be equally applicable andv use.- ful in locks ofother types. I have shown at 10 vthe usual lock casing in whichis mounted. a latch bolt l1-having. a 4stem v12 surrounded byfa coil spring 13.,which reacts against the shoulder on thefor'ward 2 ,showling mechanism isdesi'gnated by the nu-- portion of the stem and against a pair of lugs 14 upon the lock case to normally protract the latch. Upon the rear end ofthe stem is mounted a cross-head 15, which may begengaged by a' finger 16 upon a sliding;

yoke 17, operated by the usuall roll-back 18 to retract the latch bolt when the door is to be opened. A coil spring 19 surrounding a stem in the sliding yoke normally maintains the yoke in its forward or inoperative position. I.

The dead bolt `2O is shown in this insta-nce as mounted in the upper part of the casing 10 above the latch bolt land it is provided with, a stem 21y of peculiar shape which projects upwardly toward the upper part of the casing andis provided with an arni 22 directed rearwardly in a generally horizontal direction. This arm 22 is provided with anotch 23 into which projects a controlling linger .24 which is La part of the operating slide of the controlling mechanism. y y

yThe controllingv mechanism is designated as a whole by the numeral 25'and, aswill be .apptarentrconsists of the entire controlling' (mechanism for .the bolt (in this instance, the dead bolt) so mounted that it may be placed in the lock casing and removed therefrom as a unit without disturbing the parts heretofore described. The removable feature, however, of this controlling mechanism is not of importance as far as the particular invention described in this application is concerned, as the various partsof this mechanism may be'permanently mounted within the lock case, if desired.` This controlling mechanism in this instance consists of a frame composed of the two plates 26 and 27 connected by suitable posts 28, although the details of construction of thisframe are not important and in the application of the broad principles of the invention,it may not be necessary to have a. frame at all. This frame, is in the yform shown,v positioned within the lock casing by the plates 26 and 27V thereof being placed within depressions or wells 10a and 1()b formed in the front and rear -walls of the lock casing,.however, either suitable positioning or securing means may be provided, if desired. i y A y Upon one of the posts 28 are pivoted a plurality of swinging tumblers 29 urged to their normal or lower position shown` in Fi'gf2 bysuitable springs 30A which react against Lanother of the posts 28. ,vThese ti'i'mblers are provided upon their forward faces jwith,suitable recesses 31, the purpose of which will be hereinafter explained. y

.Theoperating slider of thev lock controlmeral.V and is slidablylmounted upon the frame by virtueof v,slots 33, 34and 35 formed therein through which eertainof the posts' 28 project. Near the rear end of this slide are provided talons 36', which arev adapted to be engaged by the bit 37' of the key. The slide, as has already been stated, carries the controlling lingerv 24 so vthat when the slide is moved forwardly by the key, the bolt 2O will be protracted. A shoulder 38 is provided upon the forward lower corner of this slide and has a beveled upper surface 39 adapted to be engaged by a complemental surface 40 formed upon the lower portion of a swinging detent 41 pivotally mounted upon one of the posts 28. This detent is normally urged by the spring 43 into engagement with the shoulder 38.

This swinging detent is provided with a lug 42V which extends acrossthe face of the tumblers, as is clearly shown in Figs. 5 and 6, and is adapted to be received in the recesses 31 in the face of the tumblers when these recesses are aligned, and movedto the proper position by the key bit. When the tumblers are in this position, the pressure of the key bit upon the operating slide 32 will impart a'forward'motion to this slide, and due to the beveled upper surface ofthe shoulder 38, the swinging dete'nt will be movedclockwise about its` pivotal point, the lug 42 entering the recesses 31 andthe lower portion 40 being lmoved' upwardly a suflicient extent to allow thel shoulder/"38 of the slide to pass thereunder. The slide will then be vmoved forwardly by the key', the controlling finger 24`acting to protract the' bolt.

Thebolt stem may, if desiredbe provided with a small tongue 44, which fits into a recess 45 in the operating slide32 to provide a more secure connection betweenthe bolt stem and slide.

It will be noted that the recesses 31 provided in the forward faces of the various tumblersy 29 are so arranged that the tumblers may be moved to the proper position topermit movement of the det/ent"v 41 by'a plurality` of keys, for instance, both of the keysO and 51 shown in Fig. 8, may be used' to operate the lock. The key shown at 51 may be termed a master key, as" this key may be used to operate a plurality of locksv of this type, only one of which may be operated by key 50'. It will be apparent ythat my improved controlling mechanism may be used in con-` nectionwith av dead bolt, as shown, or the controlling finger may be mounted in posi,-v

While I 4have shown anddescribed some preferred'embodiments of my invention, the same is not limited thereto in all of its details, but is capable of many modiiications and variations which lie within the spirit of the invention and within the scope of the appended claims.
